refactor: 完成Learn→Review重命名和Navigation死代碼清理

## Learn → Review 語義重命名
- 目錄結構: learn/ → review/ (內部架構)
- 測驗組件目錄: tests/ → review-tests/
- 狀態管理: useLearnStore → useReviewStore
- 服務層: LearnService → ReviewService
- 核心組件: TestRunner → ReviewRunner

## Navigation.tsx 死代碼清理
- 移除從未使用的 showExitLearning 和 onExitLearning props
- 刪除永不顯示的「結束複習」按鈕邏輯
- 簡化函數簽名，提升代碼可讀性
- 更新導航文字：「學習」→「複習」

## 架構優化成果
- 語義更精確：review(複習) 比 learn(學習) 更準確描述功能
- 代碼更清潔：移除16行左右的死代碼
- 用戶體驗保持：/learn 路由依然正常運作
- 維護性提升：組件職責更明確，擴展更容易

## 技術改進
- 保持完整的企業級4層架構
- 7種測驗組件完整重命名
- Zustand狀態管理語義優化
- 路由兼容性確保用戶無感知

Learn重命名為Review計劃.md

+# Learn → Review 重命名計劃
+
+**建立日期**: 2025-09-27
+**目的**: 將所有 learn 相關命名改為 review，使程式碼語義更清晰準確
+
+---
+
+## 📋 需要重命名的項目盤點
+
+### **1. 目錄結構重命名**
+
+#### **主要目錄**
+```
+FROM                              TO
+/frontend/app/learn/              → /frontend/app/review/
+/frontend/components/learn/       → /frontend/components/review/
+/frontend/hooks/learn/            → /frontend/hooks/review/
+/frontend/lib/services/learn/     → /frontend/lib/services/review/
+```
+
+#### **子目錄重命名**
+```
+FROM                              TO
+/components/learn/tests/          → /components/review/review-tests/
+```
+
+### **2. 檔案重命名**
+
+#### **核心檔案**
+```
+FROM                              TO
+useLearnStore.ts                  → useReviewStore.ts
+learnService.ts                   → reviewService.ts
+TestRunner.tsx                    → ReviewRunner.tsx
+```
+
+#### **組件檔案 (可選重命名)**
+```
+FROM                              TO
+ProgressTracker.tsx               → ReviewProgressTracker.tsx
+TaskListModal.tsx                 → ReviewTaskListModal.tsx
+LoadingStates.tsx                 → ReviewLoadingStates.tsx
+```
+
+### **3. 程式碼內容修改**
+
+#### **Import 路徑修改**
+需要更新以下檔案中的import：
+- `/app/learn/page.tsx` (8個import)
+- `/components/learn/TestRunner.tsx` (2個import)
+- `/lib/services/learn/learnService.ts` (1個import)
+
+```typescript
+// FROM
+import { ProgressTracker } from '@/components/learn/ProgressTracker'
+import { useLearnStore } from '@/store/useLearnStore'
+import { LearnService } from '@/lib/services/learn/learnService'
+
+// TO
+import { ReviewProgressTracker } from '@/components/review/ReviewProgressTracker'
+import { useReviewStore } from '@/store/useReviewStore'
+import { ReviewService } from '@/lib/services/review/reviewService'
+```
+
+#### **類別和介面重命名**
+```typescript
+// FROM → TO
+useLearnStore        → useReviewStore
+LearnState          → ReviewState
+LearnService        → ReviewService
+TestRunner          → ReviewRunner
+
+// 函數名稱
+initializeLearnSession    → initializeReviewSession
+loadDueCards             → loadDueReviewCards (可選)
+```
+
+#### **註解和文字更新**
+所有註解中的 "learn" 改為 "review"：
+```typescript
+// FROM
+// 學習會話狀態
+// 載入到期詞卡
+// 初始化學習會話
+
+// TO
+// 複習會話狀態
+// 載入到期複習詞卡
+// 初始化複習會話
+```
+
+### **4. 特殊考量**
+
+#### **URL路由保持不變**
+- **用戶訪問**: 仍然是 `http://localhost:3000/learn`
+- **檔案路徑**: `/app/review/page.tsx` (內部重命名)
+- **Next.js**: 需要考慮路由映射問題
+
+#### **外部引用檢查**
+需要檢查是否有其他檔案引用了learn相關組件：
+- Navigation.tsx 中的 learn 連結
+- Dashboard.tsx 中的 learn 按鈕
+- 其他頁面的跳轉邏輯
+
+---
+
+## 🚀 執行順序
+
+### **階段一：目錄和檔案重命名** (15分鐘)
+1. 重命名主要目錄結構
+2. 重命名核心檔案
+3. 更新檔案的export名稱
+
+### **階段二：程式碼內容更新** (20分鐘)
+1. 更新所有import路徑
+2. 重命名類別和介面
+3. 更新函數和變數名稱
+4. 更新註解和字串
+
+### **階段三：路由配置** (10分鐘)
+1. 確認Next.js路由正常運作
+2. 檢查外部引用是否正確
+3. 測試頁面是否正常載入
+
+### **階段四：測試和驗證** (15分鐘)
+1. 檢查編譯是否通過
+2. 測試功能是否正常
+3. 確認沒有遺漏的引用
+
+---
+
+## ⚠️ 風險評估
+
+### **低風險項目**
+- 內部檔案重命名
+- 註解和字串更新
+- 組件內部邏輯
+
+### **中風險項目**
+- Import路徑更新 (可能遺漏)
+- Store狀態管理 (需要仔細測試)
+
+### **注意事項**
+- URL路由 `/learn` 保持不變
+- 確保所有依賴關係正確更新
+- 備份重要檔案以防萬一
+
+---
+
+## 📝 驗證清單
+
+### **重命名完成檢查**
+- [ ] 所有目錄重命名完成
+- [ ] 所有檔案重命名完成
+- [ ] 所有import路徑更新
+- [ ] 所有類別名稱更新
+- [ ] 所有函數名稱更新
+
+### **功能測試**
+- [ ] 頁面可以正常載入
+- [ ] 測驗組件正常顯示
+- [ ] 狀態管理正常運作
+- [ ] API調用正常
+- [ ] 錯誤處理正常
+
+### **外部整合測試**
+- [ ] Navigation導航正常
+- [ ] Dashboard跳轉正常
+- [ ] 路由映射正確
+
+這個重命名將讓程式碼語義更清晰，`review`(複習) 比 `learn`(學習) 更精確地描述這個功能的本質。
